Edwin Henry Lemare (9 September 1866 - 24 September 1934) was an English organist and composer who lived the latter part of his life in the United States.

He was born in Ventnor, on the Isle of Wight, and received his early musical training as a chorister and organist under his father (a music seller, also called Edwin Lemare) at Holy Trinity Church. He spent three years at the Royal Academy of Music from 1876 on a Goss Scholarship, where he studied under Sir G. A. Macfarren, Walter Cecil Macfarren, Dr Charles Steggall and Dr Edmund H. Turpin. He obtained the F.R.C.O. in 1886. He became an organ professor and examiner for the Associated Board of the Royal Schools of Music in 1892.

He gained fame by playing two recitals a day, over a hundred in total, on the one-manual Brindley & Foster organ in the Inventions Exhibition in 1884. He gave bi-weekly recitals at the Park Hall, Cardiff, from 1886; this was followed by further appointments around Great Britain.

After apparently treating church services in London as concerts, he left for a hundred-recital tour of the USA and Canada from 1900–1901, and stayed in North America for most of the remainder of his life. He also toured Europe, Australia, and New Zealand, where he helped to design the organs for Auckland Town Hall and Melbourne Town Hall. He died in Hollywood, California.
